AMD gave out the latest hotfix driver update to its recently published Catalyst 10.10 WHQL, which is a whole lot more than being just a hotfix, this time. A hotfix update is usually given out by AMD if it misses out on addressing a couple of important issues with a recently published Catalyst WHQL driver update. Catalyst 10.10c Hotfix adds early OpenGL 4.1 support, and surprisingly adds multiple game-specific performance improvements (unusual for a Hotfix).

Thats like asking, "why do they have to release new drivers, the first driver they make each generation should be perfect!" Not a perfect world, both companies hotfix, not a new thing, and numerous ones in quick succession is a good sign that they care, not the opposite. Oh yeah, also 10.10's are the first drivers released after the 6800's came out also, so extra hotfixes should definitely be expected.

Ive read some where that you need to use a registry hack to get MLAA to work on the 5xxx & previous generations of cards. I read that one guy managed to get it running on his 4850 but I havent looked into it much so I dont know if he came back with results

Thank god -- Starcraft II updates! Hopefully this will fix the crappy performance and constant "your computer is running out of VRAM" messages I've been getting (after the last SC patch), even though I'm running the game in 256mb texture mode on a 512 card.

but aparently AMD blocked the reg hacks since they probably found out that EVERYONE was using regedit to get something which is only supposed to be working on 6xxx series cards ONLY (exclusively??)

the reghack only worked with 10.10a/b, an no longer works for 10.10c BUT I found some modified drivers >>>HERE<<<

Just download the 10.10c hot fix, start and cancel the installation BEFORE it starts to install the drivers then copy and paste the files in the rar into this directory "C:\AMD\Catalyst_10.10c_Hotfix_Win7_Oct26\Packages\ Drivers\Display" and then initiate the installation from the "C:\AMD\Catalyst_10.10c_Hotfix_Win7_Oct26" folder.

I hope this helps. thats what im currently running now and MLAA takes a chunk of points off me in 3d06. however it wasnt so bad in vantage.

this is more an update for the 6xxx series cards - I wouldnt bother till they come out with the official 10.11 pack. you can if you want but you wont be able to get the MLAA working. unless you can get the 10.10a installation package

Stop crapping about AMD drivers i would rather have a company that fixes things than one that leaves it broken, its really not hard to update and i still haven't had problems with crossfire.

Like said this is more for 6 series cards and 5 series, though if your having Fallout NV issues or something, then I would get them just for the crossfire fixes. But since 4800's are now 2 generations old, driver updates from them are going to be just about done since they are pretty well perfected after 2 years.

It is possible to turn on MLAA on HD 4xxx cards with 10.10c, but it isn't working right. it gives only black lines across screen and it's imposible to play videos. I use this hack only to turn on Surface Format Optimisation, and it works fine.
